In our case the UPS would alert Xymon its on battery and has lost input 
power. Then it would start shutting down boxes after a few minutes 
causing box status reports to change colour and then it would shut down 
cleanly.

Everything would already be red before its turned back on again.

As part of a clean shutdown though maybe Xymon shouldn't leave stuff 
green for the duration its turned off. I've never really checked what it 
does at that point..
